Letters Patent No. 104,904, dated June 28, 1870.

The Schedule referred to in these Letters Patent and making part 0. the sam- To all whom it may concern Be it known that I, SAMUEL Vsxsroxs, of the city and county of Providence, in the gtate of Rhode Island, have made certain new and useful Improvements in the Art of Making Axle-Nuts; and I do hereby declare the following specification, taken in connection with the drawing making a part of the same, is a full, clear, and exact description.thereofi Figure 1. is a view of the nut.

Figure 2 is a view of the same before being pressed into shape.

The object of my invention is to make an axle-nut from wrought iron, and consists in the process for that purpose hereinafter described and claimed:

Axle-nuts have heretofore been made from wroughtiron by the ordinary hand-forging process, which, from itslaek of rapidity and the expense of the labor required, is now seldom, if ever employed in their manufacture.

Axle-nuts are generally cast from malleable iron, although ordinary cast-iron is sometimes used.

In my invent-ion I roll the wrought-iron in any desired manner into along strip having four equal sides, through the center of which extends a round hole.

This t-nbe thus formed is afterwards cut into pieces of the desired length, as shown in fig. 2. These pieces, after being brought to a proper degree of heat, are, by means of suitable dies and pressure, brought into the shape of an axle-nut, as shown in fig. 1, after which the thread is out upon its inside circumference. when the nut is ready for use.

Thus I produce a nut from wroughtiron by the process above described, superior to those now in use made from cast-"or malleable iron, by reason of its increased strength, and, -from the rapidity of manu-- facture, with much less expense.

The tube may, however, be rolled six-square, or in
